For some remote work, I sometimes use X11 forwarding on ssh connections, but usually don't. But, instead remebering to use the
-X flag on my ssh connection, I can also set
ForwardX11 yes to enable it by default.
My question is, is there any (significant) downside to having X11 forwarding always enabled while not actively using it?
I am using OpenSSH for this, server runs version 5.9, client 6.6.
Edit: I mean enabling it on a per host basis, in
$HOME/.ssh/config, not globally.
